Perhaps you should try some spelling variations:
"das symposion sams" » "das symposion am", "das symposion aus", "das symposion als"
"das symposium sams" » "das symposium sas", "das symposium rams", "das symposium ams", "bacus symposium sams", "texas symposium sams", "lakes symposium sams"
"acs symposium iv" » "bacus symposium iv", "lakes symposium iv", "games symposium iv", "acs symposium isvc"
"acs symposium ii" » "bacus symposium ii", "lakes symposium ii", "games symposium ii", "acs symposium i", "acs symposium ismis", "acs symposium isvc"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("acs symposium iv") OR ("acs symposium ii"))) OR ((("das symposium sams") OR ("das symposion sams")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"acs symposium iv\") or (\"acs symposium ii\"))) or (((\"das symposium sams\") OR (\"das symposion sams\"))))".
• Removing quotes may allow a broader search: (((( acs symposium iv ) or ( acs symposium ii ))) or ((( das symposium sams ) OR ( das symposion sams )))).
• Adding a wildcard symbol may retrieve word variants: (((("acs symposium iv") or ("acs symposium ii"))) or ((("das symposium sams") OR ("das symposion sams"))))*.
